Indoor Mobile Localization in Wireless Sensor Network under Unknown NLOS Errors
International Journal of Distributed Sensor Networks, 2013 Localization is one of the key techniques in wireless sensor network. One of the main problems in indoor mobile localization is non-line-of-sight (NLOS) propagation. And the NLOS effects will lead to a large localization error. So the NLOS problem is the
